A close-up view of the bioswale.

From Gritty to Green: Columbus Avenue Gets Bioswale, Sustainable Streetscape

The sidewalks of Manhattan are famous for surprises—outré fashions, bizarre dog breeds and outlandish happenings (where else would an underwear-clad cowboy have a hard time turning heads?)—but it’s not often that the sidewalks themselves cause double-takes.

Having never seen a passive house before, The Observer expected at least some clunky sign of the building’s conversion when we visited the still under-construction home a few weeks ago. But, no. No weird metal ducts or shiny solar panels. Did the future of green building really look so much like the past? Read More
